Lock status is one of the first things a used-phone buyer checks, and it changes what a device is worth. But the gap is often smaller than people expect when you sell to another person, and much bigger when you take an instant trade-in quote. This guide uses current Swappa price data to show how much more unlocked phones go for, explains why, walks through the 2026 carrier unlock rules, and helps you decide whether to unlock before you list.<\/p>\n\n\n\n
On Swappa, factory unlocked phones list for about 5% more<\/strong> than the same model listed under AT&T, T-Mobile, or Verizon. Across 12 popular iPhone, Galaxy, and Pixel models we checked on October 1, 2026, the gap ranged from slightly negative to about 11%. Trade-in quotes are a different story: unlocked phones were quoted 25 to 57% more<\/strong> than carrier phones. Sell to a buyer and lock status costs you a little. Trade in and it can cost you a lot.<\/p>\n\n\n\n Sell Your Phone on Swappa<\/strong><\/a><\/p>\n\n\n\n Lock status describes whether a phone is tied to one carrier’s network or free to work on any compatible one. It is separate from whether the phone is paid off, and separate from an iCloud or Google activation lock.<\/p>\n\n\n\n An unlocked phone<\/strong> accepts a SIM or eSIM from any carrier whose network bands it supports. There are two kinds:<\/p>\n\n\n\n A carrier-locked phone<\/strong> only works on the network that sold it until that carrier removes the lock. Phones are locked because they were financed on an installment plan, bought on prepaid service, or sold at a discount.<\/p>\n\n\n\n This difference matters on Swappa. The Unlocked<\/strong> category is only for factory unlocked phones. A phone that came from a carrier is listed under that carrier, even after it has been unlocked, with “carrier unlocked” in the headline and description. Carrier Samsung (U) models and carrier Pixels follow the same rule. So when you compare prices by carrier on Swappa, you are comparing factory unlocked phones with carrier phones, some of which are already unlocked.<\/p>\n\n\n\n For the full mechanics of how carrier locks work, see Unlocked vs. Carrier-Locked Phones: What It Means When Buying Used<\/a>. For Samsung model numbers, see Factory Unlocked Samsung Galaxy: How to Spot a Real U1 Model<\/a>.<\/p>\n\n\n\n Every Swappa prices<\/a> page breaks out active listings by carrier and storage, along with a Swappa Trade-In quote for each. We pulled those tables for 12 popular phones on October 1, 2026, compared the Unlocked category with the listing-weighted average of AT&T, T-Mobile, and Verizon, and did the same with the trade-in quotes.<\/p>\n\n\n\n
